The Ulmen Maar lies 420 meters above sea level today, covers an area of 5.5 hectares, and is 36 meters deep. The bubbles at the maar's edge demonstrate that volcanism is still active. They bear witness to a turbulent past—but rest assured, there's no eruption in sight! A wall of various rocks and ash, up to 20 meters thick, surrounds the cone. For those interested, these testimonies to this explosive past are beautifully displayed in St. Matthias Church. This unique wall, with its different colored layers and rounded inclusions, is worth seeing for more than just geologists. The slopes of the maar basin are covered with a beautiful forest, which can be explored on a circular walk. A detour to the medieval castle ruins, from which the Crusaders once launched their campaigns, is recommended. The view from the crater rim over the maar and the Eifel beyond will take your breath away. Whether after a sweaty hike or a long drive, the blue of the Ulmer Eifel lake is all too tempting in summer. However, bathing in the maar is prohibited because it is designated as a nature and water protection area.

Old Railway Tunnel "Großes Schlitzohr" near Daun At the end of the first decade of the 20th century, the railway tunnel was driven 560 meters through the mountain. 80 years later, it was converted into a cycle path. The tunnel contains several niches with rounded arches, through which the water seeping in above is drained. The sound of this water has been a part of this place for almost 100 years.

The Ulmener Maar is small but beautiful. Located in the middle of the Eifel and in the middle of the city, it is a wonderful destination. You can easily combine a walk around the maar with a walk around the neighboring Jungferweiher. Both have recently been connected by the Ulmener Maar tunnel, which runs under the A 48 motorway.

The egg-shaped ejected particles are 6 cm or larger and deform the layers of earth when impacted. They are clearly visible here on the rock walls.

A visit is worthwhile both in summer and in winter. However, the Ulmener Maar is a nature reserve, which is why bathing is strictly forbidden here!

The first volcanoes were active in Boos around 40 million years ago. The last volcanic activity was only about 8,000-10,000 years ago. Countless tracks and the two maars can be found in the area of the Booser Doppelmaartour. The lava bomb shows in an impressive way what happened to the rock layers when a lava bomb was hit.
